With Maher Smart, Ferti 8000 and Cicl\u00f3n, <strong>irrigation can also be scheduled on demand<\/strong> based on the value recorded by the tensiometer.<\/p>\n<p>The agricultural tensiometer works filled with water. By introducing the ceramic part to the depth at which the measurement is to be taken, <strong>the water inside the cylinder is captured by the soil<\/strong>, generating a suction inside the cylinder that is measured by the vacuum gauge. The pressure measured by the vacuum gauge is what the root must overcome to capture water from the soil.<\/p>\n<p>The tensiometer indicator is graduated from 0 to 100, where each unit represents one hundredth of atmosphere. The unit of measure is centibar or kilo pascals.<\/p>\n<ul>\n<li>Values close to zero indicate saturated soils. These values are usually given after periods of intense rain or after irrigation.<\/li>\n<li>Between 10 and 20 centibar indicates that the soil is in field capacity. When the permissible depletion level is reached, irrigation must be applied. It depends on the soil type:\n<ul>\n<li>Sandy soils: this value is between 20 and 30 centibar<\/li>\n<li>Loamy soils: between 30 and 50<\/li>\n<li>Clay soils: between 50 and 70 centibar<\/li>\n<li>Higher values indicate water scarcity<\/li>\n<\/ul>\n<\/li>\n<li>When applying irrigation, the phase the crop is in must be taken into account. For example, when the plant does not have fruit, it may require more water than during the fruit setting or swelling phase. The advice of an agronomist is recommended for correct use.<\/li>\n<\/ul>\n<h2>Agricultural tensiometer maintenance<strong><br \/>\n<\/strong><\/h2>\n<ul>\n<li>Change the water in the tank and add algaecide as it is consumed.<\/li>\n<li>Expel any bubbles using the membrane at the bottom of the vacuum gauge.<\/li>\n<li>Correctly store the tensiometer monitor when not in use. For temporary storage of a few weeks, it is recommended to clean the outside of the ceramic tip with a damp towel and submerge it in a bucket of distilled water.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>The agricultural tensiometer is a sensor used in agriculture <strong>to measure the effort that the roots must make<\/strong> to extract moisture from the soil.<\/p>\n<p>An <strong>agricultural tensiometer<\/strong> has three parts:<\/p>\n<ul>\n<li>A hollow cylinder<\/li>\n<li>A porous capsule<\/li>\n<li>A vacuum gauge, which shows the tension inside the cylinder<\/li>\n<\/ul>\n<p>The <strong>agricultural tensiometer helps to save water<\/strong>. To understand how this saving is made, a comparison can be made of moistening the soil with the absorption of water by a sponge. The sponge only retains a certain amount of water, absorbing it in a few seconds. If it is placed under a tap for an hour, more water cannot be absorbed or held for longer. This is similar to soil. Although <strong>soil takes longer to absorb water<\/strong>, the principle is the same. Any excess water that is applied is wasted by seepage or evaporation.<\/p>\n<p>Probably the greatest water saving obtained from using agricultural tensiometers comes from <strong>saving unnecessary or excessive irrigation<\/strong>. Many farmers find that they had been over-irrigating certain areas while under-irrigating others. Correcting these situations results in surprising water savings.<\/p>\n<p>&nbsp;<\/p>\n<p><a class=\"eModal-1 boton_contacto\" href=\"#\"> I WANT INFORMATION<\/a><\/p>\n","protected":false},"featured_media":1841,"template":"","meta":[],"product_cat":[257,257,257,257,257],"product_tag":[],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v19.3 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Agricultural Tensiometer | Soil Moisture for Irrigation in Agriculture<\/title>\n<meta name=\"description\" content=\"The agricultural tensiometer measures the effort of the roots to extract moisture.
